So, imagine you're me and you're having some friends for tea. Or you can be you, it really just depends how often you have people round for tea. Okay, whoever you are, you're trying to remember which biscuits and tea you bought, so to not waste anything, or because you're me and you like logic - again, the choice is yours. And some knowledge of British Biscuits is needed, if you're me and you're a Brit and you've bought biscuits. Not tea though, tea's easy (unless you have your mates complaining you made it wrong, in which case, you battle it out - for hours)
